Hardcoded navigation and all routes bound to `/root`

[wozzer72]

Navigation between the components relies on hard coded routes. Ultimately, the routes should be aliased, even if it's an imported JS module of constants.

Also, every route is bound to /root; login, registration and establishment. It would make to introduce a hierarchical namespace on all root, grouping them by application function. This probably extends not just to the routes, but to the directory structure of features too.
